Edward Bellamy's Looking Backward 2000-1887 (published in 1887) was very widely read and remarkably influential for a utopian novel. It seems pretty clear that it influenced social reformers of the 1890s. Says the author of the preface to the Modern Library edition:
...this one novel included most of the reform ideas of Bellamy's generation, expressed in a form so attractive and with a social system so seemingly capable of attainment that the book immediately became the focal point of innumerable idealistic schemes...
(Robert Shurter 1951:vii)

Looking Backward is mostly concerned with social reform, and only implicitly with the nuts and bolts of what we might think of as technology. There are a couple of passages that have specifically technological content, and so are worth quoting at length for our purposes:

"All our stores are sample stores, except as to a few classes of articles. The goods, with these exceptions, are all at the great central warehouse of the city, to which they are shipped directly from the producers. We order from the sample and the printed statement of texture, make, and qualities. The orders are sent to the warehouse, and the goods distributed from there."

"That must be a tremendous saving of handling," I said. "By our system, the manufacturer sold to the wholesaler, the wholesaler to the retailer, and the retailer to the consumer, and the goods had to be handled each time. You avoid one handling of the goods, and eliminate the retailer altogether, with his big profit and the army of clerks it goes to support. Why, Miss Leete, this store is merely the order department of a wholesale house, with no more than a wholesaler's complement of clerks. Under our system of handling the goods, persuading the customer to buy them, cutting them off, and packing them, ten clerks would not do what one does here. The saving must be enormous."

"I suppose so," said Edith, "but of course we have never known any other way. But, Mr. West, you must not fail to ask father to take you to the central warehouse some day, where they receive the orders from the different sample houses all over the city and parcel out and send the goods to their destinations. He took me there not long ago, and it was a wonderful sight. The system is certainly perfect; for example, over yonder in that sort of cage is the dispatching clerk. The orders, as they are taken by the different departments in the store, are sent by transmitters to him. His assistants sort them and enclose each class in a carrier-box by itself. The dispatching clerk has a dozen pneumatic transmitters before him answering to the general classes of goods, each communicating with the corresponding department at the warehouse. He drops the box of orders into the tube it calls for, and in a few moments later it drops on the proper desk in the warehouse, together with all the orders of the same sort from the other sample stores. The orders are read off, recorded, and sent to be filled, like lightning. The filling I thought the most interesting part. Bales of cloth are placed on spindles and turned by machinery, and the cutter, who also has a machine, works right through one bale after another till exhausted, when another man takes his place; and it is the same with those who fill the orders in any other staple. The packages are then delivered by larger tubes to the city districts, and thence distributed to the houses. You may understand how quickly it is all done when I tell you that my order will probably be at home sooner than I could have carried it from here."

"How do you manage in the thinly settled rural districts?" I asked.

"The system is the same," Edith explained; "the village sample shops are connected by transmitters with the central county warehouse, which may be twenty miles away. The transmission is so swift, though, that the time lost on the way is trifling. But, to save expense, in many counties one set of tubes connect several villages with the warehouse, and then there is time lost waiting for one another. Sometimes it is two or three hours before goods ordered are received. It was so where I was staying last summer, and I found it quite inconvenient."[2]

[2] I am informed since the above is in type that this lack of perfection in the distributing service of some of the country districts is to be remedied, and that soon every village will have its own set of tubes.

"There must be many other respects also, no doubt, in which the country stores are inferior to the city stores," I suggested.

"No," Edith answered, "they are otherwise precisely as good. The sample shop of the smallest village, just like this one, gives you your choice of all the varieties of goods the nation has, for the county warehouse draws on the same source as the city warehouse."

And of music:
When we arrived home, Dr. Leete had not yet returned, and Mrs. Leete was not visible. "Are you fond of music, Mr. West?" Edith asked.

I assured her that it was half of life, according to my notion.

"I ought to apologize for inquiring," she said. "It is not a question that we ask one another nowadays; but I have read that in your day, even among the cultured class, there were some who did not care for music."

"You must remember, in excuse," I said, "that we had some rather absurd kinds of music."

"Yes," she said, "I know that; I am afraid I should not have fancied it all myself. Would you like to hear some of ours now, Mr. West?"

"Nothing would delight me so much as to listen to you," I said.

"To me!" she exclaimed, laughing. "Did you think I was going to play or sing to you?"

"I hoped so, certainly," I replied.

Seeing that I was a little abashed, she subdued her merriment and explained. "Of course, we all sing nowadays as a matter of course in the training of the voice, and some learn to play instruments for their private amusement; but the professional music is so much grander and more perfect than any performance of ours, and so easily commanded when we wish to hear it, that we don't think of calling our singing or playing music at all. All the really fine singers and players are in the musical service, and the rest of us hold our peace for the main part. But would you really like to hear some music?"

I assured her once more that I would.

"Come, then, into the music room," she said, and I followed her into an apartment finished, without hangings, in wood, with a floor of polished wood. I was prepared for new devices in musical instruments, but I saw nothing in the room which by any stretch of imagination could be conceived as such. It was evident that my puzzled appearance was affording intense amusement to Edith.

"Please look at to-day's music," she said, handing me a card, "and tell me what you would prefer. It is now five o'clock, you will remember."

The card bore the date "September 12, 2000," and contained the longest programme of music I had ever seen. It was as various as it was long, including a most extraordinary range of vocal and instrumental solos, duets, quartettes, and various orchestral combinations. I remained bewildered by the prodigious list until Edith's pink finger tip indicated a particular section of it, where several selections were bracketed, with the words "5 P.M." against them; then I observed that this prodigious programme was an all-day one, divided into twenty-four sections answering to the hours. There were but a few pieces of music in the "5 P.M." section, and I indicated an organ piece as my preference.

"I am so glad you like the organ," said she. "I think there is scarcely any music that suits my mood oftener."

She made me sit down comfortably, and, crossing the room, so far as I could see, merely touched one or two screws, and at once the room was filled with the music of a grand organ anthem; filled, not flooded, for, by some means, the volume of melody had been perfectly graduated to the size of the apartment. I listened, scarcely breathing, to the close. Such music, so perfectly rendered, I had never expected to hear.

"Grand!" I cried, as the last great wave of sound broke and ebbed away into silence. "Bach must be at the keys of that organ; but where is the organ?"

"Wait a moment, please," said Edith; "I want to have you listen to this waltz before you ask any questions. I think it is perfectly charming"; and as she spoke the sound of violins filled the room with the witchery of a summer night. When this had also ceased, she said: "There is nothing in the least mysterious about the music, as you seem to imagine. It is not made by fairies or genii, but by good, honest, and exceedingly clever human hands. We have simply carried the idea of labor saving by cooperation into our musical service as into everything else. There are a number of music rooms in the city, perfectly adapted acoustically to the different sorts of music. These halls are connected by telephone with all the houses of the city whose people care to pay the small fee, and there are none, you may be sure, who do not. The corps of musicians attached to each hall is so large that, although no individual performer, or group of performers, has more than a brief part, each day's programme lasts through the twenty-four hours. There are on that card for to-day, as you will see if you observe closely, distinct programmes of four of these concerts, each of a different order of music from the others, being now simultaneously performed, and any one of the four pieces now going on that you prefer, you can hear by merely pressing the button which will connect your house-wire with the hall where it is being rendered. The programmes are so coordinated that the pieces at any one time simultaneously proceeding in the different halls usually offer a choice, not only between instrumental and vocal, and between different sorts of instruments; but also between different motives from grave to gay, so that all tastes and moods can be suited."

"It appears to me, Miss Leete," I said, "that if we could have devised an arrangement for providing everybody with music in their homes, perfect in quality, unlimited in quantity, suited to every mood, and beginning and ceasing at will, we should have considered the limit of human felicity already attained, and ceased to strive for further improvements."

"I am sure I never could imagine how those among you who depended at all on music managed to endure the old-fashioned system for providing it," replied Edith. "Music really worth hearing must have been, I suppose, wholly out of the reach of the masses, and attainable by the most favored only occasionally, at great trouble, prodigious expense, and then for brief periods, arbitrarily fixed by somebody else, and in connection with all sorts of undesirable circumstances. Your concerts, for instance, and operas! How perfectly exasperating it must have been, for the sake of a piece or two of music that suited you, to have to sit for hours listening to what you did not care for! Now, at a dinner one can skip the courses one does not care for. Who would ever dine, however hungry, if required to eat everything brought on the table? and I am sure one's hearing is quite as sensitive as one's taste. I suppose it was these difficulties in the way of commanding really good music which made you endure so much playing and singing in your homes by people who had only the rudiments of the art."

"Yes," I replied, "it was that sort of music or none for most of us.

"Ah, well," Edith sighed, "when one really considers, it is not so strange that people in those days so often did not care for music. I dare say I should have detested it, too."

"Did I understand you rightly," I inquired, "that this musical programme covers the entire twenty-four hours? It seems to on this card, certainly; but who is there to listen to music between say midnight and morning?"

"Oh, many," Edith replied. "Our people keep all hours; but if the music were provided from midnight to morning for no others, it still would be for the sleepless, the sick, and the dying. All our bedchambers have a telephone attachment at the head of the bed by which any person who may be sleepless can command music at pleasure, of the sort suited to the mood."

"Is there such an arrangement in the room assigned to me?"

"Why, certainly; and how stupid, how very stupid, of me not to think to tell you of that last night! Father will show you about the adjustment before you go to bed to-night, however; and with the receiver at your ear, I am quite sure you will be able to snap your fingers at all sorts of uncanny feelings if they trouble you again."
