Going through boxes of old catalogs et al, I came upon some Siemens data books published in the 1970s, and I'm wondering if there is any reason not to recycle the paper. There are four 6" by 8.25" paperback books:
"Schaltbeispiele" (in German) is a bunch of circuit design examples. I probably got these while working in Sweden. I have two copies, one "Ausgabe 1977/78" (192 pages, with a sticker saying it was provided by their Stockholm office), the other "Ausgabe 1978/79" (229 pages, no sticker). The circuit examples are different.
"Design Examples of Semiconductor Circuits", Edition 1978/79. Is the English translation of "Schaltbeispiele Ausgabe 1978/79", 221 pages.
Data Book 1980/81 (in English), 591 pages.
