Read a catalog excerpt example: The Dawn of Amateur Radio in the U.K. and Greece: A Personal View — Themes and Context
Thales had studied astronomy in Egypt so he was able to draw up accurate tables forecasting when the River Nile would be in flood. But he first became widely known by anticipating an eclipse of the sun for May 585 B.C., which happened to coincide with the final battle of the war between the Lydians and the Persians. He had used some tables drawn up by Babylonian astronomers, but he did not succeed in forecasting the exact day (May 28th) or the hour of the spectacular event. It can well be said …

How these choices and excerpts are prepared
Choices use stored catalog measurements. Estimates vary with reading speed. A shared category is a catalog label, not a claim that two books have the same argument or literary quality.
Search reads excerpt text stored with this catalog and links to its associated Gutenberg record. The connection is stored in the site database; this tool does not recheck that every excerpt is word-for-word identical to that external record. Excerpt search does not cover every chapter and does not verify historical publication dates.

Do more with this book catalog
This library holds 92 public-domain works on the history of engineering and technology, spanning four main fields: civil, mechanical, electrical, and inventions. The texts range from practical manuals to historical surveys, each offering a window into how earlier generations built, powered, and moved things.
The reader tools on this page are designed to help you find a book that fits your interests and available time. You can match works by subject and length, compare two books side by side, or get an honest estimate of reading time based on the text itself.

Ways the catalog data becomes useful
Book Finder
Filter by category, subject, and length to see works that match your interests. The catalog includes 34 titles on inventions and industry, 20 on civil engineering, and 19 each on mechanical and electrical technology.
Compare Books
Place two books next to each other to compare word count, reading time, number of sections, and sentence complexity. Useful for deciding which text suits your purpose, whether you want a full treatise or a shorter overview.
Reading Time
See how long a book is likely to take based on word count and a typical reading speed. The median book here runs about 40,500 words, or roughly 177 minutes of reading.
Choosing a Path through the IHUAS Historical Engineering Library
The IHUAS Historical Engineering Library holds 92 books on the machines, materials, and methods that shaped modern industry. With four categories—Civil Engineering, Electrical Technology, Mechanical Engineering, and Inventions Industry—the collection ranges from practical manuals to historical surveys. Deciding where to start can be as much about your available time as your interest in a particular subject.
Three tools work together to help you navigate this collection. Book Finder narrows the catalog by the criteria that matter to you. Compare Books places two or three titles side by side so you can see how their lengths and structures differ. Reading Tracker turns a chosen book into a manageable daily plan. Each tool serves a distinct purpose, and using them in sequence can turn an overwhelming shelf into a focused reading list.
Start with Book Finder
Book Finder is the natural entry point because it filters the catalog by category, length, reading time, chapter rhythm, sentence flow, and subjects. For instance, if you are curious about the history of road construction, you can select the Civil Engineering category and the subject Roads to see titles like "A practical treatise on coach-building historical and descriptive — Background and Themes" (id 300) and others that match. The tool also lets you express no preference on any criterion, which is useful when you are open to discovery.
Once you have a shortlist, you can inspect each book's details to see its word count, estimated reading minutes, number of text sections, and average sentence length. These numbers give you a sense of the book's scale and density before you commit. A book with 22 text sections and a 26-word average sentence, for example, will read differently from one with 2 sections and 16-word sentences.
Refine with Compare Books
Compare Books is best used after Book Finder has produced a few candidates. It lets you select two or three books and view their metrics side by side. This is particularly helpful when you are torn between titles that seem similar in subject but differ in length or structure. For example, you might compare a 93-page manual with a 400-page history to see which fits your reading schedule.
The comparison also highlights text sections and sentence flow, which are descriptive of how the book is organized, not its quality. A book with many short sections may be easier to dip into, while one with long continuous chapters might require a larger time block. These differences matter when you are planning your reading, and Compare Books makes them explicit.
Plan with Reading Tracker
After you have chosen a book, Reading Tracker helps you set a daily page goal and monitor your progress. It estimates total pages from the word count (using 250 words per page) unless you enter the page count from your own edition. You can adjust the daily goal to match your available time, and the tracker calculates the estimated finish date.
Because progress is stored in your browser, you can return to the same book over days or weeks without losing your place. This is especially useful for longer works in the library, such as those that run to 400 or 600 reading minutes, where a steady daily habit is more sustainable than a marathon session.
