Moby Thesaurus List — Story, Setting & Ideas

The Documentation as User Manual

The first section of the text is not a preface but a technical specification. It explains that the thesaurus is 'compressed and distributed as a single zip file' and that after extraction, the vocabulary files are in 'ordinary ASCII format with CRLF (ASCII 13/10) delimiters.' The author addresses developers directly, suggesting 'reformatting schemes to represent the data in a more economical form, such as table of related terms whose index can be shared by many roots.' This language positions the reader as a programmer or data architect. The documentation also references the supplementary file 'roget13a.txt' as a guide for creating custom categories, reinforcing that the primary use case is computational, not literary.

The Sample Record: A Microcosm of the Database

The excerpt for the root word 'frill' offers a concrete glimpse into the thesaurus's structure. The record begins with 'frill,' followed by a comma-separated list of synonyms that includes 'addition, adornment, amenity, beading, beauties, bedizenment, binding, bonus, bordering, bordure, bravery, chiffon, clinquant, colors, colors of rhetoric, crease, creasing, crimp, crisp, decoration, dog-ear, double, double over, doubling, duplication, duplication of effort, duplicature, edging, elegant variation, embellishment, embroidery, enfold, expletive, extra, extra added attraction, extra dash, extravagance, fat, featherbedding, festoons, figure, figure of speech, filigree, filling, fillip, fimbria, fimbriation, fine writing, finery, flection, flexure, floridity, floridness, flounce, flourish, floweriness, flowers of speech, flute, fold, fold over, folderol, foofaraw, f...' The list is exhaustive and includes both common and obscure terms, from 'beading' to 'fimbriation.' The alphabetical ordering is strict, and the record ends abruptly mid-word ('f...'), indicating the excerpt is truncated. This sample demonstrates the thesaurus's ambition: to capture every conceivable synonym, regardless of rarity.

The Licensing Appendix: A Second Frame

The closing portion of the text is the Project Gutenberg License, a legal appendix that governs the distribution of the work. It includes instructions for copying, displaying, and creating derivative works, and it specifies that the work is 'for the use of anyone anywhere in the United States and most other parts of the world at no cost.' This appendix serves as a second frame for the thesaurus, reminding the reader that the data is public domain but subject to specific terms. The license also references the Project Gutenberg Literary Archive Foundation and its mission to 'increase the number of public domain and licensed works that can be freely distributed in machine-readable form.' This context reinforces the thesaurus's identity as a freely available digital resource, not a commercial product.

Reading the Thesaurus as a Data Structure

For a first-time reader approaching Moby Thesaurus II, the key is to recognize that the text is a database, not a narrative. The opening documentation provides the schema: each record is a root word followed by synonyms in ASCII alphabetical order, delimited by commas and carriage returns. The sample record for 'frill' illustrates this schema in action, while the licensing appendix establishes the legal framework for use. Together, these sections guide the reader to treat the thesaurus as a tool for lookup or computational processing. The absence of any thematic organization or editorial commentary means that the reader must supply their own purpose—whether that is finding synonyms for a specific word, building a natural language processing application, or studying the history of English lexicography.

Moby Thesaurus II is best approached as a dataset to be queried rather than a text to be read. The opening documentation, the sample record, and the licensing appendix each serve a distinct function: the first explains the format, the second demonstrates the content, and the third governs the use. A first-time reader should start by understanding the record structure, then explore the data for a specific root word, and finally consult the license to ensure compliance. This orientation will make the thesaurus a practical resource rather than an overwhelming list.

Skimming the Moby Thesaurus’s flat, orderly rows, I felt that peculiar stillness of a catalog—every word filed away, waiting. It reminded me of an old Victorian list, its pages promising voyages rather than taking them. I found myself reaching for Macmillan & Co.'s General Catalogue of Works in the Departments of History, Biography, Travels, and Belles Lettres, December, 1869 — Inside the Classic, another quiet register of possible worlds.
