Do more with this book catalog
This catalog gathers 91 public-domain works on historical engineering and technology. The books span four areas: inventions and industry, civil engineering, mechanical engineering, and electrical technology. Whether you are tracing the rise of aviation, the spread of canals, or the early days of wireless, these texts offer primary material from the people who built and documented those developments.
Beyond the books themselves, the catalog includes tools to help you find, compare, and plan your reading. You can sort by subject, length, reading time, and other traits. The goal is to make it easier to explore a collection that ranges from short pamphlets to substantial handbooks, all with their original illustrations and technical detail.

Ways the catalog data becomes useful
Compare titles
See how two books differ in scope, reading time, and style. Helps you decide which one to start with or how they complement each other.
Plan your reading
Get estimates of how long each book will take based on word count and typical reading speed. Handy for scheduling your study time.
Choosing, Comparing, and Tracking in One Place
The OFUFA Historical Engineering Library holds 91 books on industrial and technical history, from workshop manuals to engineering biographies. Three tools sit at the center of the collection: Book Finder, Compare Books, and Reading Tracker. Each serves a different part of the reading process, and using them together can turn a vague interest into a manageable plan.
Start with Book Finder
Book Finder is the entry point. It lets you filter by category, length, estimated reading time, chapter rhythm, sentence flow, and subject. The catalog's four categories are uneven in size: Inventions Industry holds 34 titles, while the other three hold 19 each. That means a filter on Inventions Industry will return a broader set, and you may want to add a length or time filter to keep the list focused.
For example, if you are curious about industrial processes, you might find Notes Upon Indigo — Text and Context (id 257) in the Electrical Technology category, despite its subject being indigo dyeing. The catalog's categories do not always match intuition, so the Finder's subject filters can help locate works like this that sit at the edges of a category.
Refine with Compare Books
Once you have two or three candidates, Compare Books lets you see them side by side. You can check word count, estimated reading time, text sections, sentence flow, chapter rhythm, and subjects. These are descriptive metrics, not quality ratings. A book with a high average sentence length, for instance, may demand more careful reading, but that is not a judgment on its value.
Comparing also reveals structural differences that affect pacing. A title with many short sections might be easier to pick up and put down, while one with fewer, longer sections might suit a longer sitting. The tool makes these differences visible before you commit.
Plan with Reading Tracker
Reading Tracker is for after you choose. It records progress in pages, with a current page, total pages, and a daily goal. If the catalog does not have a fixed page count, it estimates one based on 250 words per page. You can override that with the total from your own edition.
The tracker calculates remaining time and finish days based on your daily goal. Because it stores history in your browser, you can track a long project like a multi-volume work without needing an account. It does not track sections or minutes, so your page count is the single measure of progress.
A Practical Sequence
A typical workflow might be: use Finder to narrow the catalog to a few promising titles, use Compare to see which one fits your available time and reading style, then use Tracker to set a daily page goal and monitor your progress. The tools do not rate quality, but they help you find what you can actually read and finish.
