However, if one takes a closer look, it is easy to see all the ways people continue memory keeping even if it doesn't fall strictly within the definition of traditional scrapbooking as defined here. Some examples include the advent of Smash books created by EK Success, which in some ways, are a closer representation to original scrapbooks in that they are wire bound books in a variety of sizes consisting of blank printed background papers into which one can journal and glue mementos into. Another variation is the introduction and growth of pocket scrapbooking, most well known and represented by Project Life created and introduced by Becky Higgins. Higgins created the system in response to her personal desire to continue record the lives of her children and family, but in a quicker, more simple way that allowed her the flexibility to complete the project, but still in an attractive, cohesive way. One of the newest trends into scrapbooking is bringing the layout designs down to a much smaller size. Small enough to carry in a small bag with on the go updates and area for creativity and memory keeping. A traditional traveler's notebook is a simple leather cover with a band to keep closed. The cover can hold up to six inserts which can be used in many ways. The notebook has grown in popularity, allowing for journaling and memory keeping for any interests. Mini albums are another great way of memory keeping and a new trend in scrapbooking. They can be made in different sizes based on the number of photos to be put inside the album. These mini albums can be constructed and hand made from scratch. The most important scrapbooking supply is the album itself, which can be permanently bound, or allow for the insertion of pages. There are other formats such as mini albums and accordion-style fold-out albums. Some of these are adhered to various containers, such as matchbooks, CD cases, or other small holders. When scrap artists started moving away from the "page" and onto alternative surfaces and objectives, they termed these creations "altered items" or now simply called "off-the-page". This movement circles back to the history of art from the 1960s when Louise Nevelson was doing "Assemblages" with found objects and recycled parts. Modern scrapbooking is done largely on 12 inch (30 cm) square or letter-size (US Letter (8.5 by 11 inch) or A4 (210 by 297 mm)) pages. More recently, smaller albums have become popular. The most common new formats are 6, 7, or 8-inch (15, 17.5, or 20 cm) square.
