From Wiki: The name derives from a legal service begun by Frank Shepard (1848-1902) in 1873, when Shepard began publishing these lists in a series of books indexed to different jurisdictions. Initially, the product was called Shepard’s Adhesive Annotations. The citations were printed on gummed, perforated sheets, which could be divided and pasted onto pages of case law. Known as “stickers,” these were literally torn to bits and stuck to pertinent margins of case reporters. By the early 20th century, the Frank Shepard Company was binding the citations into maroon volumes with Shepard’s Citations stamped in gold on their spines, much like the ones still found on library shelves.[1] Under the leadership of William Guthrie Packard, the company endured the Great Depression and continued to grow. It moved to Colorado Springs in 1948; in 1951, it adopted the name Shepard's Citations, Inc.[2] In 1996, Shepard's was purchased by LexisNexis (a subsidiary of Reed Elsevier since 1994). " So it is a word. Albeit spelt wrongly.
