Narrowing the Stacks: Using the Finder’s Filters

The Book Finder is the entry point to AEXBI’s 96 public domain titles. It lets you filter by category, length, reading time, chapter rhythm, sentence flow, and subject. With so many books, these filters are not just conveniences—they are the difference between browsing aimlessly and finding a book that fits your current mood, schedule, and attention span.

What makes this Finder useful is that every criterion is grounded in the actual text. Word counts, estimated reading minutes, text sections, and average sentence length are all computed from the catalog data. So when you filter, you are not guessing; you are responding to measurable differences.

Start with Category and Commitment

The four categories offer a broad sense of content, but they don’t tell you how long a book will take. That’s where the length and time filters come in. The catalog has 33 short books, 17 medium, 23 long, and 23 epic. Time-wise, 32 are quick reads, 14 steady, 31 immersive, and 19 marathon. If you have an afternoon, you might set length to 'short' and time to 'quick.' If you’re planning a weekend immersion, 'long' and 'immersive' might be better.

The two filters work together. A book like Cambridge Pieces — A Closer Reading is 20,821 words, which falls in the 'short' range, and its estimated reading time is 91 minutes, a 'quick' read. That combination makes it a natural choice for a single sitting. On the other hand, Letters to a daughter — Inside the Classic is 39,685 words, still 'short' by this catalog’s definition, but its 173-minute reading time edges into 'steady' territory. The Finder lets you see that nuance instantly.

Use Chapter Rhythm and Sentence Flow to Gauge Pacing

Beyond raw length, the Finder offers two subtler filters: chapter rhythm and sentence flow. Chapter rhythm refers to how many text sections a book has—low, middle, or high. Sentence flow is based on average sentence length, also divided into low, middle, or high. These are descriptive, not evaluative; they tell you about the texture of the prose.

For example, Cambridge Pieces — A Closer Reading has only 2 text sections (low chapter rhythm) and an average sentence length of 32.1 words (high sentence flow). That suggests long, flowing paragraphs with few breaks—a book you might read in long stretches. In contrast, Letters to a daughter — Inside the Classic has 17 sections (middle rhythm) and a 19.8-word average sentence (low flow), which might feel more conversational and easier to dip into. If you know you prefer short chapters or quick sentences, these filters help you find books that match.

Subject Filters for Thematic Precision

The subject filter is the most precise tool in the Finder. It lets you search for books on specific topics, such as 'Essays,' 'Presidents -- United States -- Inaugural addresses,' or 'Authors, English -- 19th century -- Correspondence.' This is especially useful when you have a particular interest or are researching a theme.

For instance, if you are interested in American essays from the 20th century, the subject filter will pull up the 9 books that match. That includes titles like Prejudices, fifth series and Prejudices, fourth series, both by H.L. Mencken. Or if you want inaugural addresses, you’ll find Abraham Lincoln’s Second Inaugural Address and Franklin Delano Roosevelt’s 1933 address. The Finder makes it easy to assemble a mini-collection on a topic without scrolling through the entire catalog.
