The 1987 edition was another previous year's textbooks. Introduction to Elementary Particles , by D.J. Griffiths, 1987. Another well-known text. More theoretical than Perkins. Gauge Theories in Particle Physics , by I.J.R. Aitchison and A.J.G. Hey, 1989.
Early chapters are probably most useful.
Weak Interactions of Leptons and Quarks , by E.D. Commins and P.H. Bucksbaum 1983. Lots of interesting topics covered. Weak interactions of quarks and leptons.
