I'm still on the search for the ultimate clipboard manager. Namely, one that tracks your clipboard content and serves as a temporary repository for longer-form text that you need to save for a short period of time. In my search, I stumbled upon CopyClip from Fiplab, a no-frills app that'll log the snippets you send to your clipboard.
By default, CopyClip logs the last 80 items you have copied and shows the last 20 in the menu bar. You can change this value, if you need access to more than 20 copied items. This isn't a free-for-all to show 1,000 items, as the length of the list is limited by the size of your screen. You need ample room to display more than 20 clipboard contents in the app's menu. For example, I could only retrieve a maximum of 35 items on my 13-inch MacBook Air.
To use CopyClip, you click on the app in the menu bar, select the item that is stored and then paste the content where you need it. It's a bit inconvenient to have to click on the menu bar to access your copied items, but that is how the app is designed to work.
Items are stored in this copy list even when you quit the app or restart your computer. If your copy list is cluttered and you want to start with a fresh slate, you can hit "Clear" to delete everything in one click. One other handy feature is an exclusion list which ignores copied content in select apps.
CopyClip isn't as robust as its competitors, but it is very stable and unobtrusive. It does what it advertises -- keeping a log of your most recent copied items and saving them for you to reuse. Because it requires a few steps to access your list of copied items, CopyClip is not for the power productivity user. It is perfect for the user who occasionally needs to access their copied items. It's for those who need to retrieve a URL they forget to paste in their browser window or an email draft they copied and then accidentally deleted.
CopyClip is available for free from the Mac App Store.
