Encyclopaedia is a reference work that contains information on all branches of knowledge or that treats a particular branch of knowledge in a comprehensive manner. — Encyclopædia Britannica

Encyclopaedistics or encyclopaedics as a discipline, is the academic scholarship of encyclopedias as sources of encyclopedic knowledge and cultural objects as well; in this sense, this discipline is also known as “encyclopaedia studies” and can be termed as “theoretical encyclopaediography” by analogy with theoretical lexicography. Encyclopaedistics as a practical activity (profession or business) also called “encyclopaedic practice” is the process of assembling encyclopaedias available to the public for sale or for free (encyclopaedia publishing or practical encyclopediography). In this sense, it is the art or craft of writing, compiling, and editing the paper or online encyclopedias. — Wikipedia

(Gallimaufries of facts to explore,
Alphabetically stored,
Comprehensively broad)
Were a staple of sales (door-to-door). — Rusty
