Within the Scribner Library, there were a number of sub-series:
Books for Young Readers (1962): young adult titles
First Editions (1962): books by new authors that appeared in cloth and paper simultaneously
The first First Editions from 1962 on were not part of the Scribner Library, but Scribner evidently reprinted them in, I think, 1969 or 1970 as part of the Scribner Library with SL numbers from SL 177 to SL 182.
Headline Editions (1964/1968): books on current issues
The first of these Headline Editions were part of the Scribner Library but did not have SL numbers: a "Specially Abridged" edition of Polsby & Wildavsky's Presidential Elections (1964), Shinn's Tangled World (1965), and Bennett's Foreign Policy in Christian Perspective (1966).
The Headline Editions from 1964-1966 later received SL numbers as they were reprinted: SL 163 - Tangled World (1968), SL 164 - Foreign Policy in Christian Perspective (1968), and SL 605 - Presidential Elections (1976).
Omnibus Volumes (1965): treasuries, readers, and collected volumes
Lyceum Editions (1968): authoritative titles in religion, science, history, literary criticism, and other areas
Emblem Editions (1969): practical and entertaining books on popular subjects like gardening, cooking and domestic arts, and mathematical recreations
Contemporary Classics (1970): recent classics of literature
Scribner Garden Library (1971): titles by gardening expert Jack Kramer
Illustrated Classics: classic literature illustrated by artists like N.C. Wyeth, Maxfield Parrish, and Ethel Francis Butts
There were at least 2 box sets that collected SL titles:
Galsworthy (SL3, SL206, SL207, SL208, SL209, & SL210)
Churchill - Marlborough (SL270, SL271, SL272, & SL273)
Evidently, the series numbering ended with the 1979 titles -- and possibly with SL 900, a nice even number. After 1979, only ISBNs identify titles in Scribner Library ads.

Charles A. Madison, Book Publishing in America 422 (1966):
In 1960 the firm launched the Scribner Library, a series of paperback reprints from its rich backlist in fiction, belles-lettres, and religion. These books sold widely, particularly in colleges, and soon became one of the firm's most profitable ventures.
