Now EndNote ships with thousands of styles, but if you can't find the one you are looking for, there are a couple of things you can do. First of all, you might want to check if the style you want has been newly created after your version of EndNote was released. You can go to endnote.com, "Downloads", and "Output Styles". So these are all the styles officially supported by EndNote. This list is constantly updated, and new styles are being added all the time. I can use the search and browse function here to find the style I want. If I find one, just click on the "Download" link, and a dot ens file will be downloaded. Open the file. So these are the details of this style. Now I can go to "File", "Save As", "Save", and now the downloaded style file has been moved to a location where EndNote looks for styles that are not originally shipped with EndNote. It is usually in your "Documents" folder, under "EndNote", "Styles". Now if I open up style manager, I can now search and find my new style, right here. Sometimes you have a style in EndNote, but a more recent version of that style is available on endnote.com. Styles are constantly being updated. The process of getting an updated style to EndNote is the same as getting a new style. You search for the style, download it, open it, and save it. Again the newer style goes to your "Documents" folder, under "EndNote", "Styles", and the older version will not be deleted, and is still in the application's styles folder. However the style manager will only display the most recent version, which is this one here. Now sometimes there just isn't a ready- made style for you, and you will need to create it yourself. Fortunately, most of the time a custom style is based on an existing style with just a few modifications. You almost never need to create a style from scratch. So let's say I am going to create a style based on the "APA 6th" style. Let's say my publisher or my institution requires that the issue number be not displayed in the bibliography, and that all electronic articles must have either a DOI number OR a "Retrieved from" message with database name. So let's fix this. Let's find the original APA 6th style using the style manager. So go to "Edit", "Output Styles", and "Open Style Manager". Now if APA 6th is your current style, you will have it right here as a menu item, but I am going to show you how to edit any style, whether it is your current style or not. Search for "APA 6th", select, and click "Edit" here. These are all the options you have in making your own style. So the first thing to fix here is that we need to remove the display of issue number from bibliography entries for journal articles. So I can go to "Bibliography", "Templates", and you can see a list of reference types, and their corresponding templates for bibliography entries. The first one is "Journal Article". We don't want the issue number, so I will just remove "Issue" together with parentheses and the pipe separator. Now we have another reference type to fix, and that is "Electronic Article". Again we are going to remove the issue with the parentheses. I am going to remove the "Retrieved from" element here, because we don't want it to display all the time. We only want it to display when there is no DOI available. So we are going to remove that, and the URL and the spaces and pipes associated with them. Just like that. Now we still have to take are of the logic that if there is no DOI, a "Retrieved from: [Database Name]" message should be displayed. We can do that in "Field Substitutions". So I can say if the DOI field is empty, use "Retrieved from:", I am going to get rid of the URL field and insert a new field here, which would be "Name of Database". OK. We're done! This style will print a bibliography without issue numbers for electronic articles and journal articles, and it will display DOI number if the article has one, and if not, the message "Retrieved from: [Name of Database]" will be displayed. Let's save this. "File", "Save As". Because you created a style based on one that originally shipped with EndNote, you should give it a different name, so that the original APA style is left intact. I am going to say "APA 6th LW", and you can name it anything you want. Click "Save", and my new style is saved to my "Documents", "EndNote", "Styles" folder. Here it is. And I can access that from my style manager here. I am going to make that one of my "favorites", so that it shows up in my short list. So let's test this out. Here is my "Groundbreaking Paper" again, and I have my citations in the original APA 6th style. You can see that the issue number is displayed in parentheses after the volume number. Now I am going to switch to my new style, and you can see that the issue number disappeared, and because this particular one has a DOI, it does not display the "Retrieved from:" message. Another one that doesn't have a DOI. And you can see that it does display the "Retrieved from:" message. Another example. Now let's say you are required to use the JAMA style for your thesis, and you are also required to have a bibliography at the end of each chapter. All you have to do is to edit the existing JAMA style. Again go to "Edit", "Output Styles", "Open Style Manager", and search for "JAMA". Click "Edit". Now under "Sections" on the left, you have several options here. You can create a complete bibliography at the end of the document, which is the default. You can also create a bibliography for each section. If you choose that, you can also decide whether you want the numbering of references to continue or start afresh for each bibliography. Or if required, you can create a bibliography at the end of each section, and a complete bibliography at the end of the document, in which case, you have no option but to let the numbering continue. In this example, I am just to going to choose the second option, and choose to start numbering from 1 for every section. Now save the style with a different name. I am going to call this "JAMA Sections". OK. Now I can go to my word document and make sure that each of my chapters is in its own section. I can go to the end of each chapter and insert a section break. I can go to the end of each chapter and insert a section break. Just like that. Just like that. Now if switch my style to the newly created "JAMA Sections" style, and after EndNote updates the bibliography, you can see that I indeed have a bibliography at the end of every chapter, and they all start from number 1. Now to sum up, if a style you want is not in the 6000+ styles shipped with EndNote, you can do a couple of things to get it. You can check endnote.com to see if there is a new style created after your version of EndNote was released. You can check if there is a recently updated style to an existing style you have that matches what you want. Or you can create your own style based on an existing style.
