Single sheet, 220 x 85mm, printed on both sides with manuscript insertions. Good copies (two with loss to lower right corner (cancellation?) and one to left edge with a little loss of printed text; variously folded, creased and soiled). Mostly similar size and format, excepting one on green paper and sized 145 x 75mm but with identical printed text, this nice survival illustrates no only Library administration at the British library (Museum) but also the readership of the reader, John Sachs. The verso lists eight rules that "Readers Are Particularly Required" to observe John Sachs was an illustrator, wood engraver and seal designer and worked for, amongst other publications, The Boys Own Paper, and produced designs for the Universal Exhibition of 1867. His consultations included works on heraldry, archaeology, reptiles, poetry and maps.
