Yes, if you value rigor. If you are studying physics or engineering, a modern book like Stewart is fine. But if you are a budding mathematician who wants to understand why limits work the way they do, Bers is a treasure. It sits beautifully between the conversational tone of Spivak and the computational focus of Thomas.
However, do not break the law or risk your computer's security for a PDF. Use the Internet Archive’s borrowing system or buy a $15 used copy. Once you hold that orange and white Holt, Rinehart and Winston cover in your hands, you will understand why so many mathematicians are nostalgic for this forgotten classic.

Step 1: Standard Search Engines
Use quotes: "Lipman Bers" "Calculus" filetype:pdf
Often, university math clubs host the PDF on their alumni servers. Look for *.edu domains.
Step 2: The Internet Archive (archive.org) Search for "Lipman Bers." The Internet Archive often has scanned borrowing copies. You can "borrow" the PDF for 1 hour or 14 days legitimately. This is the most legal way to read the PDF online. Yes, if you value rigor
Step 3: The "Solutions Manual" Trap Many searches for the PDF are actually searches for the Solutions Manual (written by Frank Fleck). That is even rarer. Do not confuse the two. The textbook itself is sufficient; the solutions manual is a ghost.
Before we discuss the PDF, we must understand the man. Lipman Bers (1914–1993) was not just a calculus teacher; he was a titan of 20th-century mathematics. Born in Riga, Latvia, Bers survived the Soviet gulags and Nazi occupation before fleeing to the United States. He became a leading figure in complex analysis and a human rights activist.

Bers taught at Columbia University and the Courant Institute of Mathematical Sciences. He believed that calculus was not a collection of tricks for engineers, but a beautiful, logical structure. His textbook, Calculus (published by Holt, Rinehart and Winston in 1969 and again in 1976), was his attempt to present that beauty to undergraduates.
